1p OoS + 1p another faction
Opponents skip next planning phase.
Now why would you skip 2 turns to make your opponent skip one? Well your opponent doesnt know youre skipping 2 turns, turn 9 they dont realize you are gonna ramp, turn 10 they think maybe you might calamity. With more 11 cost cards means more cards to guess. Now when you play it, you know the opponent cant dodge or block with more than they already have blocking. It makes for a perfectly predicted turn where your opponent does nothing.
Plus you can also ramp up if you splash in some WP for a meaty swing. Play your big stuff, protect in support zone play this for guarantee swing.
Flame dawn, maybe youre about to be puffyed, well play calamity, then play this. GG easy win.
DoD use this to stall for another turn to morale the crap outta them.
